Another Stereosonic death

A man died from a suspected drug overdose at the Adelaide Stereosonic festival on Saturday. Two more men are in a serious condition. It follows the death of Sylvia Choi at Sydney's Stereosonic, and brings the total death toll from drugs at music festivals this year to five. Seventeen people were admitted to hospital from suspected overdoses after the Brisbane Stereosonic show on Sunday.

Around midday on Saturday, 19 year-old Stefan Woodward was taken to the Royal Adelaide Hospital. He later died.

Police released an image of the drugs found on him to serve as a warning for others.

A 20 year-old man and a 21 year-old women are both in a critical condition in hospital following the Adelaide festival; police say they're being treated for serious overdoses.

Stefan's mother Julie Davis, said in a statement their family was devastated by the loss.

Stefan finished a traffic management training course on Friday and was excited about getting an apprenticeship. I keep asking what could have stopped me from losing my son, and my other two sons from losing their darling brother. More than anything I want something good to come of this tragedy. I want organisers of events like these to make sure there is enough first aid on offer to make sure that no one gets turned away, and no one feels they need to wait. I want friends to look after each and make sure it's never considered weak to ask for help. I want authorities to make sure kids are kept safe with free water. And I want young boys and girls like Stefan to never be too scared to ask for help. Mostly, I never want another family to go through what we are going through next now - Julie Davis.

South Australian Police are trying to work out if the three people had taken the same drugs.

"We are frustrated in the wake of this man's death," Superintendent John De Candia said.

"I specifically said before the event that police did not want to be advising any family of such a tragedy.

"If you want to be 100% certain, you don't take them. You don't know how they are made, the people that manufacture them are in the business of organised crime and making money. They don't care about the consequences."

"We cannot express our concerns highly enough regarding the dangers of drug use. We have tragically lost two lives to drugs during our festival and whilst every effort has been made to protect you and keep you safe with our teams of professional medical and security staff, you as individuals need to make smart choices and understand the risks you are taking," the post said.

"As media reports have indicated there are various highly dangerous substances on the market and there is no way of knowing what is in them. Do not gamble with your life today."

Queensland Police said they arrested 116 people on 144 charges at the Brisbane show. Of these, 125 were drug related charges, with five charged with the supply of dangerous drugs. Officers found between 30 and 100 MDMA pills, as well as cash, on some of those charged.
